The 1989 Kiel Convention of the IPA

In 1989 a meeting was held in Kiel, Germany, that was of great importance to the subject of phonetics. This was a special Convention of the International Phonetic Association, organised by the Phonetics Department of Kiel University under Professor Klaus Kohler. I have been looking at my copy of the official group photo taken near the end of the Convention and trying to remember the names of the people in it. A few years ago there was an attempt made by some fellow-phoneticians to get the names listed, but I have lost any record of that so I am trying again. You can see the picture and the list of names so far here. It would be good to have more names - please add as comments to this post if you know any.
Wikipedia used to have an article on the 1989 IPA Convention, but it has now been absorbed into the article History of the IPA. I am hoping to put this photo, with information on the participants, into this article if I can get copyright permission to use it.
